Trivia

Ellen McLain, at her 'So You Broke My Heart and Killed Me' panel during Anime West 2011, revealed that she was originally asked to voice the Anger Core. It was later decided that Mike Patton, lead singer of the alternative metal band Faith No More, should voice the core, as McLain's voice "just couldn't sound mean enough" for the part.[1]

In Portal 2, Aperture Science Bombs bear a striking resemblance to the Anger Core. The Bomb shares an "angry" animation with the Anger Core, making it possible that the Core was to make a reappearance in Portal 2 at some point during development.
